STUDIES IN CAMBRIAN GEOLOGY AND PALEONTOLOGY. 



Tn my reports for the past two years reference has been made to 

 studies of the older sedimentary rocks of the North American Conti- 

 nent, which I have been carrying on as opportunity offered for more 

 than twenty years. This work was continued in Montana and the 

 Canadian Rockies during the field season of 1908. 



Outfitting at Belton, Mont., the last of June, 1908, the party pro- 

 ceeded with saddle horses and pack mules north past Lake McDonald 

 and on up the valley of the North Fork of the Flathead River to the 

 Kintla lakes. From the Continental Divide northeast of Upper 

 Kintla Lake beautiful views were obtained of the higher peaks, deep 

 canyons, and -now fields north and south of the international bound- 

 ary. Numerous photographs and notes on the geology were taken. 



The party crossed the forty-ninth parallel and moved north up the 

 valley of the Flathead, in British Columbia, making several side 

 excursions into the mountains. The farthest point reached toward 

 the northeast was about 20 miles south of Crows Nest Pass. From 

 there the route led along a trapper's trail up Johnson Creek to the 

 Continental Divide, thence to the town of Pincher Creek and south 

 to Waterton Lake. An examination was made of the oil fields west 

 of Waterton Lake on Cumberland Creek, which is about 15 miles 

 north of the international boundary. From this point the party 

 followed a trail along the western side of Waterton Lake and thence 

 up Little Kootna Creek to the Continental Divide at the head of 

 Mineral Creek, a tributary of McDonald Creek. A few days were 

 spent in taking photographs and examining the geological structure 

 in this vicinity before returning to Belton, on August 1, for supplies. 



A trip Avas next made by the way of Lake McDonald to Gunsight 

 Pass on the Continental Divide, above Upper St. Mary Lake. But 

 smoke from forest fires became so dense that the party returned to 

 Belton and proceeded southward up the South Fork of the Flat- 

 head River for about 100 miles. Examinations were made of Gordon 

 Mountain and vicinity and during the return journey several geo- 

 logical sections were examined along the western side of the Conti-' 

 nental Divide. Belton was again reached early in September and a 

 trip was made, to Marias Pass, which afforded a very fine view of 

 the main range of the Rocky Mountains along the line of the Great 

 Northern Railway. 



The scientific results of the 950-mile trip through the forests and 

 on mountain trails will aid materially in the solution of several prob- 

 lems connected with the stratigraphy and structure of the main ranges
